Kanye West shares favorite song of 2015 -- And you'll never guess who the artist is

The "All Day" rapper tweeted on Sunday that his favorite track of 2015 was Justin Bieber's hit, "What Do U Mean?"

While we're not sure why it took West until March to make this announcement, it does confirm what we already suspected: no one is immune to new Bieber.

But the real question is whether or not the Yeezy accolade was a higher honor than Bieber's Kids' Choice Award for Favorite Male Singer, which the Canadian singer scored on Saturday.

While he didn't go on one of his now-familiar Twitter sprees, West did drop another bomb via Twitter on Saturday. The father-of-two announced plans to buck the fashion industry's scheduling traditions by "going Mad Max" and doing away with a fashion calendar altogether, writing that he'll release six collections in one year.

The 38-year-old rapper is no stranger to non-traditional approaches, having blazed his own trail with the Yeezy Season 3 fashion show-slash-record-release party during New York Fashion Week in February. (We still have so many unanswered questions about that show...)
